论中国古典音乐“天人同构”艺术精神的文化情趣

中国传统关学思想精髓可谓是从现实生活立足的、具有实用体征的、内容与形式融合贯通的哲学思辨体系,更注重艺术理应遵循于特定的伦理学和美学的价值规范。可以说,“天人合一”的中华传统文化的精神“潜质”,也是华夏审美文化的“中坚思想”,它在人类文明历史长河中成为艺术精神流变的一种支配力量与文化底蕴,始终渗透于中国古典音乐审美的诸多时空。因此,中国古典音乐崇尚“天人同构”的自由、和谐、恒定、隽永的生命状态,并成为东方艺术苑囿中一朵靓丽的文化奇葩。     

李代数的等价表示

定义了两个李代数表示的等价的概念,证明了复数域CH 的两个半单李代数L1和L2如果具有等价的表示,那么L1与L2同构,由此推出一个重要结果;若U（L1）≌U（L2）,则L1≌L2。     

对"汉字屋论证"逻辑结构的五种诊断模式

美国哲学家J.R.塞尔(Searle)于1980年提出的"汉字屋论证"(Chinese Room Argument,以下简称为CRA)目前早已成为人工智能哲学的经典话题之一。二十七年以来,反驳CRA的学者往往致力于揭露CRA本身的形而上学前设的错误,却不太去检讨CRA本身的逻辑形式。而美国学者郝泽(Hauser)与英国学者丹普尔(Damper)虽然就CRA的逻辑形式提出了总计四种诊断模式,却都没有正确地揭示出CRA的真正错误。本文将在他们的基础上提出对于CRA逻辑结构的第五种诊断模式,并由此论证:CRA之所以失败,乃是因为塞尔并未根据该论证的内在要求而在"汉字屋系统"与"计算机系统"之间建立起一种恰当的同构关系来。     

同构、P-态射、互模拟与模态等价性

结构的模态等价性是指这些结构上有效性的模态公式恰好相同.本文比较了模型之间的三类关系:同构、P-态射、互模拟,从而得出互模拟关系概括了最大范围的模态等价性,因为模型之间的互模拟关系包含它们之间的同构关系和P-态射关系.同时,对框架等价性也给予了一定的研究,得出结论是:同构的框架一定是模态等价的,但具有另外两种关系的框架不一定是模态等价的.     

Institutional isomorphism and nonprofit managerialism: For better or worse?

Nonprofit organizations (NPOs) have increasingly adopted business‐like practices as a response to institutional pressures. Some researchers argue that this development leads to mission drift, whereas others find a positive effect on organizational performance. However, the institutional pressures responsible for shaping the nonprofit sector have remained hard to distinguish from each other. This study explores the consequences of mimetic, normative, and coercive pressures, and looks at how they affect managerialism, organizational performance, and mission drift. We link these concepts through a structural equation model based on survey data and find that one aspect of managerialism, strategic behavior, is a key construct in influencing the response to isomorphic pressures and can positively affect organizational performance while holding off‐mission drift. Normative isomorphism even has a direct positive effect on organizational performance. Mission drift can take place when organizations are under coercive pressure without having strategies or internal processes in place. These findings imply that organizations should invest in their strategy and the professional development of their staff to increase organizational performance and avoid mission drift.     

An optimality criterion for supersaturated designs with quantitative factors

A supersaturated design (SSD) is a factorial design in which the degrees of freedom for all its main effects exceed the total number of distinct factorial level-combinations (runs) of the design. Designs with quantitative factors, in which level permutation within one or more factors could result in different geometrical structures, are very different from designs with nominal ones which have been treated as traditional designs. In this paper, a new criterion is proposed for SSDs with quantitative factors. Comparison and analysis for this new criterion are made. It is shown that the proposed criterion has a high efficiency in discriminating geometrically nonisomorphic designs and an advantage in computation.     

关于代数模与代数的扩张的注记

由可知,从已知代数模的扩张U出发,便可得一广义导子f。反之,利用这个广义导子f,我们也可构造出一个代数模的扩张U＇。本文证明了这两个代数模U与U＇是同构的。并给出了由因子系构造代数的扩张的一个方法。     

论安置教育制度的废除——对《反恐法》第30条的质疑

安置教育不是我国的刑事处罚或行政处罚,而是类似于我国劳动教养、收容教育性质的行政强制措施。安置教育是劳动教养、收容教育制度的继续,其凸显了劳动教养、收容教育制度严重侵害公民人身自由、违反诸多劳动教养、收容教育曾经违反的法律原则等重大缺陷。安置教育制度因与《反恐法》终极价值目标相悖,可能会导致愈反愈恐、导致反恐机关权力寻租以及人身危险性标准难以把握等问题出现,从而不利于反恐法的立法目的的实现。安置教育制度设置存在立法价值偏差、立法思想错误运用以及反恐方法本末倒置等不足。安置教育制度废除后,弥补措施应当包括防止违反法的价值的法律规范再现,并运用刑罚、安置帮助教育等措施弥补因安置教育废除带来的空白。     

Model identification using 27 runs three level orthogonal arrays

In this paper we examine all the combinatorial non-isomorphic OA(27, q, 3, t), with 3≤q≤13 three level quantitative factors, with respect to model identification, estimation capacity and efficiency. We use the popular D-efficiency criterion to evaluate the ability of each design considered in estimating the parameters of a second-order model with adequate efficiency. The prior selection of the ‘middle’ level of factors plays an important role in the results.
